DTV Exciter

The most complex component within a digital television transmitter, the CD-1A exciter takes incoming MPEG-2 bitstream and converts the information to a modulated 8-VSB RF signal that can be broadcast over the air.

Available for VHF and UHF applications, the CD 1A offers even more features to maximize signal coverage, performance, ease of operation and compatibility with other equipment. For example, the CD 1A uses the recently-adopted SMPTE 310M interface to accept the 19.39 megabits-per-second, MPEG-2 signal from the studio, thus ensuring compatibility with current state-of-the-art and future generations of DTV encoders and STLs. In addition, the Harris CD 1A exciter uses proprietary digital technology to generate an 8-VSB signal of superior integrity, and offers multiple levels of analog and digital correction to provide exceptional in-channel performance and maximum coverage.

Featuring a new mechanical design which provides convenient front access to all components, the exciter is easy to operate. An innovative new monitoring option can eliminate the need for costly test equipment.
